Planktonic replication is essential for biofilm formation by Legionella pneumophila in a complex medium under static and dynamic flow conditions
Article Abstract:
Surface adherence of and biofilm formation by Legionella pneumophila in a rich medium that supported axenic replication and biofilm formation by the virulent L. pneumophila strain JR32 and by clinical and environmental isolates are analyzed by confocal microscopy and crystal violet stainings. Findings indicate that biofilm formation by L. pneumophila in a rich medium is due to growth of planktonic bacteria rather than to growth of sessile bacteria.

Differential gene expression profiling of Staphylococcus aureus cultivated under biofilm and planktonic conditions
Article Abstract:
A comparative transcriptome analysis is carried out to determine which genes are up regulated in Staphylococcus biofilm cells. Physiological and biochemical tests for the up-regulation of urease, formate dehydrogenase, proteases, and the synthesis of staphyloxanthin confirmed the microarray data.

Use of merocyanine 540 for photodynamic inactivation of Staphylococcus aureus planktonic and biofilm cells
Article Abstract:
The photodynamic inactivation of Staphylococcus aureus planktonic and biofilm cells using an exogenous Ps, merocyanine 540 (MC 540) is discussed. Results of both planktonic and biofilm experiments suggest that MC 540-mediated PD1 of S. aureus is a promising treatment.
